Oil is led by the pipe (1 from seat 9, upon which a thin film of oil is fed the chamber 5 to the oil-chamber c in the from the ducts k bycapillaryattraction. Tho

air thus mixes thoroughly with the oil during its passage into the mixing-chamber m.

. The baffle-plate it acts merely as a deflector or baffle to divert the inrushing air down upon the conical seat 9, and thereby saturates or mixes the air with the film of oil upon the seat 9.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is

In a vaporizer, an oil-chamber, a pipe leading from an oil-supply and discharging into said oil-chamber, a second oil-chamber, a pipe of said air-tube adapted to permit of the free passage of air between the end of the tube and said baffle-plate, and a spring adapted to hold the baffle-plate in its normal position adjacent to said air-tube and to permit of the v ready response of said baffle-plate to the suction action of a piston to increase said airspace, an overflow-pipe connected with the first oil-chamber for regulating the height of oil in said chamber, an overflow pipe arranged in the second oil-chamber and having an adjustable extension to regulate the height of the oil in said chamber and the third chamber and to hold the same at a level differing from that'in the first chamber, a pipe connecting said overflow-pipes and adapted to conduct the surplus oil of the oil-chambers back to the source of oil-supply.

In testimony whereof I have hereunto set my signature in the presence of two subscribing witnesses.

HENRY W. TUTTLE.
